Luciana, a country girl who has moved to Milan, is married to Mario, an intellectual type who avoids her since an accident forced him to live with his torso permanently in a cast. Lonely and depressed because also of her recent dismissal, she asks for help through a letter and becomes friends with elementary school teacher Anna, who also resents the negativity of her workplace and the world around her. Meanwhile, blue collar worker Marco waits for his fellow paisan Luciana to reciprocate his feelings. The vicissitudes of this quartet intertwine with the comical interludes of a commune of hippies who live in the tunnels of the Milan subway and spend their time pulling pranks on the passers-by.

After losing a finger in a work accident, an Italian worker becomes increasingly involved in political and revolutionary groups.

After Annunziata (Angela Molina) opens up a hostel with her friend Antonio (Daniel Ezralow), she is saved from being raped by a Camorra boss as the gangster is suddenly killed. The killer escapes before Annunziata is able to see who it was. Following this murder are several others, and always with the same “signature” — a syringe in one of the testicles of the victims. As the gangsters continue to be killed off, the identity of the killer – or killers – slowly becomes obvious.
